g_object_compat_control() is undocumented, should probably be deprecated
g_object_compat_control() is public API. It's present in the introspection data and gi-docgen output, but is entirely undocumented:
We should probably deprecate it. It allows customizing the behavior of floating refs, and is used by GtkObject (GTK 1 era? OK, GTK 2 apparently!) to lift handling of floating refs from GLib up to GTK. Nobody should be doing this nowadays.
